Running Title: [C]Choline PET-CT for nodal evaluation in prostate cancer
Our goal was to develop a system that would allow us to recreate live patient arterial pathology by using an industrial technique known as stereolithography (or rapid prototyping). In industry, drawings rendered into dicom files can be exported to a computer programmed to drive various industrial tools. Those tools then make a 3D structure shown by the original drawings. We manipulated CT scan ...
Soft-x-ray cryotomography allows quantitative and high-resolution three-dimensional imaging of intact unstained cells. To date, the method relies on synchrotron-radiation sources, which limits accessibility for researchers. Here we present a laboratory water-window microscope for cryotomography. It is based on a λ=2.48 nm liquid-jet laser-plasma source, a normal-incidence multilayer condenser, ...
Nowadays many MRI scans can give 3D volume data with different contrasts, but the observers may want to view various contrasts in the same 3D volume. The conventional 2D medical fusion methods can only fuse the 3D volume data layer by layer, which may lead to the loss of interframe correlative information. In this paper, a novel 3D medical volume fusion method based on 3D band limited shearlet ...
Within an effective field theory framework we compute the most general structure of the one-loop corrections to the 4D gauge couplings in one-and two-dimensional orbifold compacti-fications with non-vanishing constant gauge background (Wilson lines). Although such models are non-renormalisable, we keep the analysis general by considering the one-loop corrections in three regularisation schemes:...
We provide optimized recursion relations for homodyne tomography. improve previous methods by mitigating the divergences intrinsic in calculation of pattern functions used previously, and detail how to implement data analysis through Monte Carlo simulations. Our refinements are necessary reconstruction excited quantum states which populate a high-dimensional subspace electromagnetic field Hilbe...
